抄録

VO<sub>2</sub>(A) micro-nanostructures have been synthesized via a facile hydrothermal method by hydrolysis of oxidovandium(2+) ethylene glycolate in malonic acid solution. The novel morphologies of VO<sub>2</sub>(A) could be readily tuned by altering the concentrations of malonic acid and reaction temperature. It is revealed that malonic acid played an important role as a structure directing agent helping the alternative formation of VO<sub>2</sub>(A). Furthermore, their electrochemical properties were investigated, which reveal that the as-prepared VO<sub>2</sub>(A) nanorods exhibit a relatively higher first discharge capacity than other VO<sub>2</sub>(A) morphologies.
